Item Build

Starting Items

Doran's Blade - Probably the best item and cost efficient item for any AD carry currently due to the 10 AD, 80 HP and + 5 HP on hit passive it provides.

Core Items

Berserker's Greaves

Breathstealer

Youmuu's Ghostblade

Infinity Edge

Greater Totem (Trinket)

Blade of the Ruined King - This item provides 3 important things to an ADC. Sustain (Lifesteal), Damage and Attack Speed. It has a passive that synergizes well with your Vault, allowing Quinn to quickly burst down squishy targets with a single combo combined with this item's passive. There little doubt that this is the best first big item for Quinn.

*Note: If you go back on your first back with enough gold to get a BF than you should buy that and build it into a BT rather than going the Botrk route. Having an early BT gives a huge AD boost that will let you win trades and get last hits much easier.

Infinity Edge - After completing your BOTRK, you can start buying high attack damage items to turn Quinn into an insane DPS machine.

Endgame Build

Berserker's Greaves

Blade of the Ruined King

Youmuu's Ghostblade

Infinity Edge

Last Whisper

Phantom Dancer

Greater Stealth Totem (Trinket)

Last Whisper - After IE this item is good to get mid-late game when the enemy team starts stacking armor because it will let you ignore a % of it. You should definitely get this before PD if you notice the enemies stacking armor; however, if you notice they aren't, you could choose to get this after your PD.

Phantom Dancer - Gives Attack Speed and Critical Chance you need to synergize with your Infinity Edge. The small movement speed bonus also helps Quinn with her kiting and positioning as well.

6th Item

Maw of Malmortius

Banshee's Veil

Guardian Angel

Randuin's Omen

If you decide you want a defensive item, what you get will depend on the game you are in. If you are against a lot of AP champs, than you'd prob get a Maw or Banshee. If you are against a mainly AD team, than a Randuins. If your team is ahead or if you are against a mix comp, than you could opt for a GA. If you feel like you need more dmg go for a BT (or a 2nd BT).

Why don't you build Static Shiv, Triforce Blackcleaver on her? You're wasting so much bonus damage with her passive. And why are you maxing E before her Q? yes you can use E more but it's not as effective as her Q which does more damage, AOE, and 2 second Blind which makes it more effective in fights because you have 2 extra hits landing before they can fully respond to it.

Because Triforce does not scale, as it only adds bonus damage based on BASE AD, its better you utilize actual items that give high amounts of damage to scale with the passive. Static Shiv is a fine substitute for PD, but PD will always be stronger in the end game. Black Cleaver in general is bad on most ADCs, bar MF and perhaps Urgot, due to the mechanics of the stacking.

From my experience, E is better because the cooldown decreases and it is much more reliable to use and hit. The Q blind only stays at 1.5 seconds regardless of the level, so the only thing that increases is the damage and the CD goes down. Overall, Q does more damage, but when used with the passive, E surpasses Q.

Yep, I agree with you on Triforce and Black Cleaver, I main Quinn and I prefer those. However, there certainly are times you want to have a different build, responding to your and enemy team composition, their builds etc. As for what to max, that's a question. Sometimes I tend to max W due to its passive, it gives you a great farming and burst potential and is especially effective when the Tag Team is on. And lower cooldown on your vision can save the game. :) I max Q when I'm positive I can take down my enemy and I want some waveclear. However, if I work with a passive supp like Soraka, Sona and such, or if I'm not confident I can win my lane, I go for E which can serve as a gap closer and an escape too. It also slows the enemy I attack so that gives me some time to think and react. Guides are really good for beginners but once you learn to play some champs, you have to start learning the game - and that means learning to adapt to the situation. If I considered the easiest route for beginners, I would probably go for Bloodthirster (BOTRK is really hard to use actually so I don't recommend it for beginners)+Last Whisper+Infinity Edge+Some speed item (I usually go for Phantom Dancer since it's easy to use and the minions don't get in my way, but there's a good waveclear potential in Statikk Shiv and there are people who like it better)+Some defensive item (Guardian Angel is always a safe pick for beginners)+boots. Max E because it's safe. That's about it. :)

With the new updates to Trinity Force's damage and movement. Would it be better to rush it for Quinn since she is kind of a caster style ADC? Or would it still be optimal to continue building the standard ADC items?

Why give an adc a Frozen Mallet? The whole point of an adc is they do not buy any defense unless it's really necessary, if it's for the passive replace it with a Trinity Force so you also gain the passive of Sheen to deal extra damage after a vault, the ability power also gives a slight boost of damage from blinding assault.

Frozen mallet gives you a lot more health than trinity force, meaning you stand a much better chance of surviving their assasin's burst, and getting that passive on every hit gives you much better kiting and chasing potential.

Mallet is really situational against champs you want to be able to kite out or chase. It's a late game item that isn't that bad for AD carries because HP and AD is really useful. The build here is just the preference of the player, you can change it up if you feel it's better for your playstyle.

How can someone say that quinn is bad agains adc's?? Her burst is AMAZING and her ult just crushes everything, and her Q blinds them wich makes you win every trade. Sure, she can have a hard time agains long range adc's but your blind make's you win every trade, maybie even secure a kill if you don't back out too early. It's hard to learn her ult. If you know where to be in teamfights you have won that teamfight.

I find Cops build to be very weak and his cons are terrible. Yes she has a melee form but she can absolutely catch a single champ completely off guard. Maxing her w second I find to be much stronger as going in should be your least desired plan but still a strong option. The execute from her ult is great because you can ult to reposition or escape and come back in if you can for a kill or even multi kill. Not to mention your plan is vault off them to get your passive out which is on a very short cd against the right comp her q crushes teams but you don't need extra damage on it till late game using it to blind so you can trade more efficiently is what I find better. I never have manna issues on her even maxing q first. Not to mention every 21 seconds reveal the lane and surrounding area or make it so someone can secure a kill by granting vision in the brush. Frankly though the ms and as from hitting someone you vaulted off can often save your life or secure a kill. Not to mention it makes catching a lone opponent quite terrifying as valor for them think e in q for the blind and auto them to death oh your low r your dead 1 less person force the fight. Your q has a shorter range but its fast and upon landing on an adc makes great time to trade her burst is amazing and with great positioning she can absolutely shut down ad heavier compositions landing your q on grouped enemies pretty much gives your team 1 and a half seconds to burst down whoever they want. Lack of range is made up for if you factor in proper play. I find BT stronger than BORK on her and Frozen is only necessary if you're having trouble securing which frankly 2 crits is a huge amount of damage with her passive. I don't generally have any problems out trading any ADC or Bruiser and teamfights I find to actually be her strength because her goal is render the ADC useless for enough time for your team to crush them or giving enough time to crush the APC while the adc can't deal damage. Her trades are incredibly efficient and thats what matters. In all honesty missing your q leaves you open for harrass from longer range champs but if you don't miss you win the trade. She is literally a champ about proper use teaching good positioning and planning. Not to mention the interrupt can be used to stop channels or stop an assassin from killing you which puts them right in position to get instagibbed. She needs looked at more in terms of value. Her mechanics are easy to understand but difficult to play if you're overly aggressive or lack tactics. Using Harrier to farm and to get extra damage in your harass is part of what makes her difficult is if you don't max your w it's very easy to get punished plus maxing it promotes using it whenever possible as it has NO COST giving near constant vision of where your team is and the surrounding area preventing bad engages revealing none stealthed champions in bushes or areas around objectives making her battlefield control very very strong.
